Study on the Evolution Characteristics of Two-Zone Failure Mode of the Overburden Strata under Shallow Buried Thick Seam Mining

Advances in Civil Engineering, 2019
There are risks of water burst and sand inrush in the working face of the Northwest Mining Area in China. Based on the 22407 working face of Halagou coal mine, the evolution characteristics and mechanism of a two-zone failure mode of the overburden ...

Putting the Femme in Feminist: Trans Feminism and the ‘Male Lesbian’ in the American Second Wave

Gender &History, EarlyView.
ABSTRACT A slur, a joke or a post‐structuralist case of mistaken identity. To the extent that the male lesbian has been discussed, she has figured dismissively. Yet throughout the period historicised as American feminism's second wave, potentially thousands of trans femmes organised under this identity. Despite being entirely overlooked in scholarship,

Folklore Studies, Fieldwork and the Making of a Domestic Anthropology in Fin‐de‐Siècle Britain

History, EarlyView.
Abstract This article follows the ‘communities of knowledge‐making’ that formed around folklore collection at the end of the nineteenth century. Often regarded as eccentric or marginal figures in the history of human science, these collectors in fact engaged in lively and sophisticated discussions about the methodologies needed to study the mental ...

Interventional oncology in children: Where are we now?

Journal of Medical Imaging and Radiation Oncology, EarlyView.
Abstract Paediatric Interventional Oncology (IO) lags behind adult IO due to a scarcity of specific outcome data. The suboptimal way to evolve this field is relying heavily on adult experiences. The distinct tumour types prevalent in children, such as extracranial germ cell tumours, sarcomas, and neuroblastoma, differ strongly from those found in ...

Study on Coal Seam Roof Failure Based on Optical Fiber Acoustic Sensing and the Parallel Electrical Method

Energies
As China enters the stage of deep coal mining, the accidents caused by roof failure pose increasingly serious threats. Current research on roof failure zones often use single methods, but single geophysical data may result in multisolution issues during ...

Caving mechanisms for a non-daylighting orebody

, 2017
The sublevel caving mining method is a mass production method with potentially very low operational costs. The success of this method is dependent on, among other factors, the cavability of the orebody and the overlying rock mass.

Study on Water Disaster Prevention and Control Technology under Condition of Extra-thick Coal Seam with Slicing Fullmechanized Caving Mining

, 2018
Some coal seams belong to cretaceous strata in the east of Inner Mongolia, China. There are obvious differences of rock characteristics and mechanical properties between Cretaceous and Carboniferous- Permian strata. The overburden failure characteristics

Brain reward function in young people with cannabis use disorder: A functional magnetic resonance imaging study

Addiction, EarlyView.
Abstract Background and Aims Cannabis use disorder (CUD) affects ~50 million people globally. Neuroscientific theories suggest that a blunted neural response to non‐drug rewards is a hallmark of substance use disorders; however, this remains untested in CUD. The current study tested whether brain reward system responses to the anticipation and feedback

Research and application of top coal caving characteristics at end of fully mechanized caving working face in hard and thick coal seam with super large mining height

Meitan xuebao
Fully-mechanized caving mining with super-large mining height is an effective method for safe and efficient mining of thick and extra-thick coal seams. Aiming at the problem of poor top coal caving ability at the end of fully-mechanized caving mining in ...
